Hey Emunator,
thank you for your great and very helpful feedback :).
So, i tried directly to fix the points you mentioned (still not all yet).
I removed the old samples, like the hihats (i dont know why i used that).
Next i played a little more with the sidechain effect, i used it before, but definitely not in the way it should be used.
So great thanks for that nice tutorial, that helped me a lot i think.
I don't know if i use it correctly now, what do you think?
At least i added more details to the background and changed the ending, but with that i'm actually not really happy, maybe i got i nice idea in the future.
So thank you again for your feedback, this is exactly the the feedback that i want :).
I think i want to submit this someday, but i'm not really sure about that, because it's not easy to change this nice original melody ;).
What do you think, am i on a good way or not?
